Helped off the ground after a bone-jarring hit by Dragons giant Mickey Paea on Monday night, concussed Gold Coast backrower Brad Meyers had an admission to make.

"Apparently he came off and told (Titans assistant) Steve Murphy `I don't know who I am'," dead-panned Gold Coast co-captain Scott Prince.

"The word came down from Carty (Titans coach John Cartwright) to Murph, `tell him he's Artie Beetson and get him back out there'."

Yep, Meyers has not heard the end of it since coming off second best to Paea.

Not that he can remember the incident.

Or his two-try heroics in the Titans' 28-24 win at Skilled Park.

"Red (Meyers) got a double but he can't remember it. We just won't tell him he scored anything," said Titans backrower Anthony Laffranchi with a laugh.

While the jokes have kept coming at training this week - at Meyers' expense - the Titans' injury list is suddenly no laughing matter.

Titans boss Michael Searle has painted a bleak picture ahead of their NRL clash with the lowly Sydney Roosters at Gosford on Saturday.

Although named in an extended Titans squad, Meyers, pivot Mat Rogers (ribs) and Luke Bailey (arm) are all in serious doubt.

"We will have a very different side to what we had on Monday night," Searle said ominously in Brisbane on Thursday.

He said Rogers was the worst of the injured ranks, considered "highly unlikely" to run out against the Roosters.

"And Meyers we've still got get to get through because of the head knock," he said.

Meyers was close to best on ground in his stunning performance, stepping up in the absence of injured backrower Mark Minichiello.

Indeed Prince hinted that Minichiello - once mooted for Origin duty - may not receive a walk up start once he recovers from an ankle injury.

The impressive performance of Luke O'Dwyer, replacing late withdrawal Ashley Harrison due to a swine flu scare, gave another indication of the Titans' depth.

"Due to the injuries we had (against Dragons) guys had to play big minutes like O'Dwyer and (Ben) Graham, who probably aren't quite used to it," Cartwright said.

"O'Dwyer was probably our best player, and Meyers best on ground until he was injured.

"It's good that we are not relying on the same players week in, week out."

O'Dwyer said he knew he had big shoes to fill once told that he was running out instead of the quarantined Harrison.

"A couple of the guys started sneezing and winking in the dressing sheds (after Harrison was quarantined)," O'Dwyer laughed.

"But we all knew that we had to dig in and give that bit extra."

Prince said they could not afford to drop their guard against the desperate Roosters.

"They have been struggling all year," Prince said.

"We don't want to be the team that plays them back into form.

"At Gosford not a lot of people will be watching but we've got to turn up with the right attitude."

In some welcome news, the Titans will welcome Harrison and flying winger Kevin "Flash" Gordon (groin) back against the Roosters.
